Hi, am having similar problems, video, man yeffects (not yet finished song), render has been running for 75 minutes. Clicking on the render completion button(bottom of screen) brings up the order and progress of the elements, i seem to be stuck/slow on the P10 render 4x4 boards.
It was working fine until had a crash a week ago and had to kill xl4 to get out.
Has been slow on this sequence ever since, other sequences no problem, computer 12 months old so not its problem (I5 skylake, 3.5 mhz, 16 meg ram, 4 gig video card)
FSEQ file is 200 meg in size , mp4 is 78meg
Any ideas to speed up or let it run over night to finish and hopefully that will correct itself once its processed its way through the sequence
Cheers Boof63
